Second, compared with eating meat, whether vegetarianism is more beneficial to human body or society may require investigation and study. The scientific methods are, of course, experimental research and statistical comparison. For example, randomly select several people and divide them into two groups. One group was vegetarian during the experiment, while the other group kept a daily diet during the experiment. Finally, compare the health data of the two groups (including the comparison between the members of each group before and after the experiment). Of course, such an experiment may be difficult to carry out, such as how long it takes for the experiment to be convincing, and it may not be easy to reach an understanding. Then, the most convenient experiment is that singles choose to let themselves eat vegetarian food for a period of time, such as one month or three months, to see what effect it has. If there is a good influence, you will accept the vegetarian statement, if there is a bad influence, you will not accept the vegetarian statement and still go back to your daily diet.
